　What are the advantages of concrete filled steel tubular structures

　　1. High bearing capacity, light weight, good plasticity, fatigue resistance and impact resistance. 2. High strength concrete can be used. The three-direction pressure avoids the brittle failure of the core high-strength concrete.

　　The inertia moment and bearing capacity are all the same in all directions, so it is suitable for the uncertain structure of earthquake and wind load.

　　3, Steel pipe core part of the concrete without reinforcement, easy to water concrete.

　　4, steel pipe in the construction phase can play a supporting role, so as to simplify the construction and installation process, saving part of the stent, to reduce the process, shorten the duration. 5, the replacement of steel compression bar can be a large number of steel savings.
